Purgatory is the final rush of our sanctification(Being made holy and perfected) by the Power and fire of Gods love(by Virtue of Christ Jesus cross) in order for us to enter heavenly glory. It is final purification. We are purged by the fire of God and spiritually cleansed in this life in suffering if we unite it to Christ in prayer and in the next if we not completely sanctified. Paul uses the analogy of fire in 1 Cor 3:10-15 to describe this reality. Heaven is like the public swimming pool, in heaven there can be no sin or anything unclean(Rev 21:27). Purgatory is like the shower you must take before entering into the swimming pool. Of coarse the soap and water is the Holy spirit cleaning you(sanctifying you) to enter into glory. All of this is done by virtue of Christ Cross. The Cross is sanctification accomplished. Purgatory and suffering on earth is sanctification applied. The fathers of the Church spoke on this as well.

God bless,

In Jesus the King through Mary the Queen Mother,
Athanasius

IS it after one has been purged of your sins that you believe you recieve the gift of justification? Will there be justified people in purgatory in your opinion?

__________________

Paul show us that those who will go through this purgatorial fire, will be saved. We believe that justification is a process to us Catholics and we believe we are justified at Baptism(1 cor 6:11) and when we have faith(Rom 3:28) and fully when we die. Purgatory is final sanctification. All who go through purging are saved people and will be saved in the fullest sense once they reached heaven.
I hope that make sense to you.

God bless you Paul.

In Jesus through Mary,
Athanaisus
